Lip reading is the ability to understand what a person is trying to convey by analyzing their lip movements, facial expressions, teeth and tongue movements, speech patterns, etc. Lip reading is considered an art.
Many people have been practicing it as an art since the 16th century. Few studies have been conducted on lip reading. Research shows that people are able to understand only twenty percent of words or sentences here. Another study shows that only five to six out of every 12 words can be understood clearly by lip reading.
It is very difficult to catch the tone and pitch of people speaking during lip reading. The same word can sometimes convey different meanings.
Researchers at a university in Iran reported that an artificial intelligence system converts visual information into sound during lip reading. Humans, on the other hand, cannot understand every word. So he tries to summarize.
Lip reading by machine is quite challenging. Because if the AI does not understand the subject’s position and motion information correctly, then the result may be different.
The AI divides the video of the subject into many images. Each image is then analyzed and provided with information.
AI can combine visual speech recognition and automated speech recognition systems. At present, research on automated speech recognition methods has been able to advance a long way. On the other hand, the visual speech recognition system is still far to be studied.
Setting up the entire model for lip reading analysis in the machine is time-consuming. In the future, artificial intelligence systems will perform better at lip reading than humans.
Just think, if you can easily understand what other people are trying to convey through AI, your life will be much easier than before. Maybe in the near future, it will be possible to understand language by directly communicating from one brain to another brain without talking to people.
